This type of <br />arrangerrent is made possible by the availability of lower <br />interest rroney and recent changes in the tax laws which allows <br />attractive investrrent tax credits to private industry for this <br />type of investment. <br /> <br />This type of arrangerrent was extensively investigated for the <br />construction of a water treatment facility for the Town of <br />Wellington. <br /> <br />b. <br /> <br />Water Quality Considerations <br /> <br />The water fran the North Poudre Reservoir No. 3 was tested on <br />October 8, 1981, January 25, 1982 and again on June 11, 1982. <br />The results of those tests are shown in Tables 3 and 4 together <br />with the test results for the existing wells and ELCO water. As <br />shown on Table 3, the North Poudre water is below all limits of <br />the Primary Drinking Water Regulations with the exception of <br />lead. However, the existing wells exceed the limits for selenium <br />and gross beta activity and are at or near the limits for cadmium <br />and lead. The significant difference betv.een these sources is <br />the fact that lead is rerroved by conventional treatment processes <br />whereas selenium and radioactivity require rrore sophisticated <br />treatment rrethods. <br /> <br />Table 4 shows the results of the tests for the Secondary <br />Standards which are not mandatory. Those results indicate that <br />the North poudre water exceeds the reccmrended limits for <br />sulfates, total dissolved solids and hardness. Therefore, any <br />plant treating water fran this source should be capable of <br />softening. The sulfate content will not be changed by the use of <br />conventional treatment rrethods. However, it is believed that the <br />majority of the sulfate is contributed by ground water infiltra- <br />tion into the Reservoir. Therefore, during the sumrer rronths <br />whe11 a substantial arrount of Poudre River water is being added to <br />the Reservoir the sulfate level will drop. 1\ddi tionall y, the <br />presence of sulfate should not be considered significant since <br />the reccm1'el1ded limit is based on the laxative effect of sul- <br />fates. Since the sulfate level of the existing wells is in the <br />sarre range as the Res. No. 3 water the town. s people have becare <br />accustorred to this level of sulfate and therefore, should not <br />experience any problems due to the sulfate level. <br /> <br />5 <br />
